3D imaging systems are currently being developed using liquid lens technology for use in medical devices as well as in consumer electronics. Liquid lenses operate on the principle of electrowetting to control the curvature of a buried surface, allowing for a voltage-controlled change in focal length. Imaging systems which utilize a liquid lens allow extraction of depth information from the object field through a controlled introduction of defocus into the system. The design of such a system… 

Three dimensional moving pictures with a single imager and microfluidic lens

This research result shows that a single imager, equipped with a fast-focus microfluidic lens, produces a highly accurate depth map that demonstrates real-time HDTV 3D movie frame rates are feasible.



Three-dimensional adaptive microscopy using embedded liquid lens.

The compact optical design of a high-resolution 3D scanning microscope with adaptive optics capability for refocusing with no moving parts designed for clinical research and can find applications in biomedical imaging, white light interferometry for surface roughness measurements, and other 3D imaging systems.

Design of an autofocus lens for VGA ¼-in. CCD and CMOS sensors

We present the design of a lens for CCD or CMOS sensors using a new generation of lenses with electrically controlled focal length. These new elements made out of liquids (a drop of oil in water)

A single-imager, single-lens video camera prototype for 3D imaging

On camera images, research showed that DfD combined with edge detection and segmentation provided subjective improvements in the resulting depth images, compared to the literature on a limited test set.
